To 11271. not it may concern;

in mom; that l, DANIEL H. Tenn, a n of the United. States, residing at rsville. in. the county of Cerro Gordo of iowa, have invented a certain new and useful Corn-Husker, of which the following i... a r-ipecification.

'l'he cli ic *3 of my invention is to provide a corn hi ng n'iachine of simple, durable ind inexpe construction,designed-to be advanced in; engage standing stalks of corn; topick up stalks of corn that are iying on the ground; to straighten stalks that are inclined laterally frointhe row; to remove the ears from the stalks; to remove the husks from the ears, and to place the ears in a conveyor that will discharge. lhei'n upwardly and laterally into wagon advanced alongside of the mechi c.

u invention consists in, the construction arrangement and combination of the vnrious parts of the device, whereby the objects conteinplntcd are. attained, as hereinafter more fully sctforthy pointed out in my claims end illustrated in the accompanying drawings in which Figure l shows side elevation of a-com-v plete machine embodying my invention. Fig. 2 shows it plan view of same- Fig. 3 shows a plan view of the machine frame. Fig". a detail perspective view of the conveyor belt provided withspring actuated lea es.

therewith to engage a sector 19 connected with the tongue.

The lever 17 is pivoted to the extension 20 of the tongue and its lower end is extended forwardly at 21 and connectcd'by a link 22 with the forward end of the frame 10 so that by shifting the lever 17, the frame 10 and tongue may be adjusted relative to each other. At the side of the frame 10 adjacent to the traction wheel 12 is the drivers seat 23. 7

On the side of the machine frame adjacent to the Wheel 15 are the guide or pick up arms, each comprising a'straight outer member 24: extended parallel with the longitudinel axes of the machine to a point near the forward end thereof and then inclined downwardlv and forwardly at 25, as shown in Fig. 1. Then beginning at the forward end of each of the parts 24 is an inner member 26 inclined rearwardly and away from the part 25 end upwardly, the body portions of said parts 26 being parallel with the longitudinal axis ofthe machine frame and being spaced apart far enough to admit rows of corn between them.

At the rear of the machine frame is a transverse shaft 27 from which all of the operative parts of the machine are driven. This shaft has a sprocket wheel 28 provided with a clutch member 29 fixed to it in line with the sprocket rim 13 and the sprocket chain 30 connects the rim 13 and the wheel .28. Mounted on the shaft is a clutchirnember'31 controlled by a rod 32 connected with the lever 3-3 which stands adjacent to the operators seat. In this way the shaft 27 may be made to operate with the sprocket wheel 28 or to stand idle when said sprocket Wheel is rotating.

Mounted on top of the embers 26 are the supporting bars 34 extendllng upwardly and rearwardly at an angle of-about forty-five degrees and supported at their rear ends by the uprights 35. Directly in front of the rear ends of the bars 34 is the cross piece 36 on which are the bearing boxes 37. These beerin boxes are designed to support the journa s 38 at the rear ends of the stalk holding rollers 39. These stalk holding rollers are each formed with longitudinal grooves of such size as to present the appear ance of a ratchet wheel and the rollers stand spaced apart far enough to engage corn stalks between them. The forward ends of said rollers, as shown in Fig. 5, are smooth and tapered at and the journals ll at the forward ends thereof are each mounted in v real-wardly and upwardly to a point of (113-- a slidin r bearing block 42 arranged in tubular gnu es 43 to permit said blocks &2 to move slightly 111 a direction transversely of the machine frame. For each block,4:2, there is an extenslble 0011 Spring 44: to normally hold the forward ends of the stalk holding rollers toward each other and yet to permit themto spread slightly against a spring pressure when necessary.

On the rear end of each roller'3tl is a beveled pinion 45 meshed with a mating pin ion 46 on a shaft 47, whieh'shaft is provlded at one end with abalance wheel 48 and chains project through the opening 62 and on its other end with a cog wheel 49. This cog wheel all) is rotated by means of a cog wheel 50 011 a shaft 51, which shaft is pro- Vided with a sprocket wheel 52 on one end and sprocket wheel on its other end. This sprocket wheel '52 is driven from the shaft 27 by means of a sprocket wheel 54 on the shaft 27 and a chain 55 connects the sprocket wheels 54 and 52. By this means, when the machine is advanced, the rollers 39 will have their adjacent faces moved downwardly and the teeth thereon will engage stalks of corn and hold the stalks in position so as to prevent them from being pulled out. of' the ground, the teeth on the rollers being arranged to prevent them from slipping rela tive to the stalks. Said rollers are inclined at an angle of about forty-five degrees and they are rotated at such speed that, as the machine is advanced, there will be no tendency for the'stalks to be pulled outof the ground forwardly. 3

. .Directly above the rollers 39 are the ear snapping bars 56 which'have their forward ends cur'ved inwardly and rearwardly toward each other at 57 and their body portions extended straight rearwardly and upwardly and spaced a art far enough to freely admit corn stal (s between them but to prevent ears of corn from passing downwardly through them. Thuswhen the ma- 1 chine is'advanced, the earsof corn will be caught by the snapping bars. 5G-and the stalks will be drawn-downwardly by the rollers 39 and the ears will be left lying upon the flat surface on top of the bars 56.

Above the ear snapping bars 56 are two upright guide boards 58 and at the tops of these 11 right guide boards are the guides 59 incline outwardly and away from each other. In the outer edges of the boards 59 near the lower ends thereof are the rollers 60 provided with projections 61 and arranged to turn with their upper portions moving in a direction towardeach other, so that cor n stalks -inclined laterally from the rows will be engaged by said rollers and forced inwardly toward the snapping bars so that said stalks will not be broken.

mounted.

I have provided means fofixpicking up fallen stalks and also for movi g the ears of corn that have been snapped from the stalks the fingers (38 thereof will engage corn stalks that are. lying near the ground and'move them upwardly toward the lower ends of the snapping bars. Fixed to the shaft 63 is a sprocket wheel69 directly above the snapping bars At the rear end of each snapping bar 56 is a shaft 70 arranged at 'right angles to the snapping bar and having thereon a sprocket wheel 71. A sprocket chain 72. is passed around the wheels 71 and 69, and is provided with inwardly projecting arms 7 3 to travel rearwardlyand upwardly directly above thesnapping bars 56.

I I have provided for driving the rollers 60 as follows: Connected with the upper end of each roller 60 is a shaft 74, said connection being by means of a universal joint 75. At the rear end of'the shaft '74 is a beveled pinion 76 in mesh with a similar pinion 77 fixed to the shaft 70. I have provided for driving this shaft 70 during the "advance of the machine frame as follows:

On the lower end of the shaft 70 is a. beveled pinion 78 in mesh with a mating pinion 79 fixed to a shaft 80. Mounted on this shaft 80 is a sprocket wheel 81 to receive the sprocket chain 82, which chain also passes around the sprocket 83 on the shaft 27.

I have provided for removing the husks from the ears as follows: The numeral 84 indicates supporting bars connected at the forward ends with thefuprights 35 and extended downwardly and rearwardly'to the uprights 85 atthgrear end of the machine. Near the forward ends of the bars 84 is a cross piece 86 on which the bearings 87 are The two husking rollers are indicated by the numeral 88 and stand side by side near enough to ea'clrother to prevent ears of corn from passing between them, but capable of ermitting the lmsks to drop downwardlyi between them.' On the forward end of the journal of each husking roller is a beveled pinion 88 in mesh with a mating pinion 89 on the shaft. 51. Each husking roller is provided with a series of annular-grooves JOund wlth a series of annularly arranged headed husklng pins 91,

eases].

the rows of pins 91 on one roller registering With the grooves 90 of the mating roller. 1 have also provided stripping devices for the husldng pins by fixing to the bars 8 the notched strippers 92 to receive the headed pins 9-1 when they are adjacent to said bars 84. The ears of corn discharged from the rearends of the snapping bars 56 will pass upon a l st plate 93 which covers the gearing devices that operate the rollers. Directly above the forward end of this plate 93 is a transverse shaft 94 having, thereon a pulley l1? This shaft is driven by means of the sprocket, wheel 95 on one end thereof connested with the sprocketvvheel 53, by the chain 93". Al; the rear ends of the bushing rollers is an idler shaft 98 having a pulley 99 thereon. An endless conveyer belt 100 is passed around the pulleys 95 and 9%) and is arranged to move with its lower portion directly above the husking rollers to thereby hold the ears of corn in position Where the hashing pins may readily engage the husks and also to advanee the ears of corn that have been hushed toward the dis charge end of the rollers. Fixed to the conveyor belt 100 at regular intervals is a series of lL-shaped plates 101, which plates are eonnested by the rivets 102 with the belt and have a porfiion projecting at right angles to the belt. Connected with each of the plates 101 is a hinged leaf 103 capable of movement from a position at right angles to the belt to a position pa 'allel with the belt, its m0vement being limited by the part of the plate 101 that stands at right. angles to the belt. Springs 104 are provided for normally holding said leaves at right angles to the belt. In this way if one of said leaves should strike upon an ear of corn when traveling rearwardly above the husking rollers and said ear of corn should have its husk engaged by the huskin r pins, then the leaf would fold and pass salt. ear and engage and move only snc' are as were free to slide.

fat the end of the heel no; rollers is a ehute 105 inclining upwardly and laterally to receive the ears of corn. in this chute is a conveys ehain 105 traveling; over a sprocket wlr 107 at the outer end of the chute and Cli'lVCIl by a sprocket Wheel 108 at the inner end of the chute. 'l his sprocket Wheel 108 is fixed to a shaft 109, which shaft has a beveled pinion 110 at its forward end in mesh with the pinion 111 on the shaft- 27. The outer end of the chute .105 is supported by means of the brace 11.2 fixed to the machine frame.

Having thus described the construction and operation of each of the elements of the machine in turn, the operation of the machine as a whole will be readily understood. x
